EVERETT — After last year’s purchase of several concrete and asphalt plants in the city, Cadman Inc. is expanding operations at two sites while closing a third.

Plans include adding a ready-mix concrete plant and dredging near the company’s north Everett location, at 222 W. Marine View Drive, to be able to bring in material by barge.

Jeff Sieg, a spokesman for the company, described the work as rearranging assets.

“The end goal is to retain our current presence to service our customers while also ensuring we are better positioned for potential growth in this key market,” he said in an email.

Cadman acquired seven quarries, five ready-mix concrete plants and two asphalt operations in the Pacific Northwest from Cemex in July 2017. Cadman, based in Redmond, operates four sites in Everett.

At its property at 6300 Glenwood Ave., the company is planning to close the existing ready-mix concrete plant by next summer. Cadman plans to sell the land after mining the sand and gravel. The listing for the 67-acre property caught the attention of Economic Alliance Snohomish County, which called it the last remaining large parcel in the Seattle metro area.

The concrete plant operations from the Glenwood site will be relocated to W. Marine View, which is anticipated to be operating by late 2019. In addition to the plant will be silos, mixing equipment, dust collection systems, a water reclaimer and a stormwater management system, according to the company. They have met with neighbors about the anticipated changes.

An asphalt plant currently operates at Cadman’s north Everett site.

Sieg estimates the new plant will generate 15-20 additional truck trips per day. That could bring a 50 percent increase over the
40 truck trips daily now.

At the north Everett site, the company also wants to start transporting incoming material over water. To do this, Cadman needs to repair an existing, but inactive, unloading berth and dredge an area about 150 by 350 feet.

Once Cadman is able to bring in sand and gravel by barge, a greater amount of material will be carried in by ship than by truck, said Christy McDonough, an environmental manager.

At Cadman’s Delta site, at 17 E. Marine View Drive, the company is planning to relocate the soil remediation operation from Glenwood. Recycled asphalt will also be crushed and stored there.
